7 tips when using glue on aquariums

Superglue is safe for aquariums. It’s generally used for joining mosses and rock. You can also add plants like anubias and java fern to hard capes like rocks and driftwood.

Here are seven significant steps you can follow while using superglue to take your aqua scaping game to the next level:

1. Use the gel version

Using the liquid version of the glue can cause a mess. It’s also harder to apply and control compared to the gel version.

Gel glue is thicker than regular glue, and you can easily manipulate it. Use the gel version for your aquarium and save yourself some trouble.

2. Don’t use too much glue

The glue generally gets a whitish color once it forms a bond underwater. Most people don’t like the look of it. That’s why you should use just enough glue that you’d need to seal the bond.

A trick to get around this is to use sand or soil. Add sand or soil to the glue as it starts to cure. It will hide the white color and give the aquarium a natural look.

3. Apply glue on the roots only

When gluing a rhizome plant, don’t apply the glue all over the plant. You can cause the plant to suffocate and end up killing it. Glue the roots instead of the entire plant, and your plant will be alive and healthy.

4. Use nitrite gloves

The issue with superglue is that it can easily stick to your hands. You can avoid it by using nitrile gloves. It’ll protect your fingers.

A word of warning is, don’t use latex gloves.

If you want to avoid using gloves, you need to be careful when applying the glue. Pour the glue on the rock or hardscape and place the plant. Use the glue bottle cap to press the plant against the hardscape.

5. Combine thread and glue

Glue is potent in forming bonds between the plant and the rock. But it’s not always enough to hold down top-heavy plants. If you have tall plants in the aquarium, they can come apart if you’re only using glue at the root.

You can use glue combined with a thread to remedy this situation. You only need to do this for the top-heavy plants where the glue’s bond may fall short. Doing this will guarantee that your plants stay where it’s supposed to.

6. Make hardscape with glue

Don’t limit the power of the glue to just adding plants with rocks. Play around with them. You can make extraordinary hardscapes by using glue.

You can attach pieces of driftwood to make it look like a tree. You can also add elements of rock together and create the perfect hardscape of your choice.

7. Apply glue before taking the object under water

Glue cures very quickly once you put it in the water. Don’t apply the glue underwater. Apply the glue first, and then put the attached objects underwater.

Hold down the objects for a few minutes to ensure they stay in place. You can then remove your hands as the glue gets cured.
